Answer:
Step-by-step explanation:
x²-x-1/4=0
or 4x²-4x-1=0
disc.=(-4)²-4(4)(-1)=16+16=32>0 ,not a perfect square.
Roots are real,different and irrational.
It has 2 roots or 2 solutions.
Answer:
Step-by-step explanation:
x² - x = 1/4
[tex]x^{2}-x -\frac{1}{4}=0\\\\a = 1 \\\\b = -1\\\\c = \frac{-1}{4}\\\\D = b^{2}-4ac\\\\ = (-1)^{2}-4*1*\frac{-1}{4}\\\\= 1 + 1\\= 2[/tex]
D = 2 > 0
So, this equation has real roots
